1 UNITED STATES FRITZ TOTZE K, or STOPPENBERG, NEAR nssmv-on-rnn-nunajGERMANY GOKE-OVEN-WALL STRUCTURE Application filed March 29, 1928, Serial no. 265,588, and in Germany February 13, 1926.

This invention relates to improvements in cokeove'n wall structures, the'object of the invention being to vprovide a gas or coke oven wall having flues therein and composed 5 of two spaced courses of stretcher bricks and connecting and interposed header bricks so constructed and arranged that the joints between the header bricks, vertically, are broken to the extent that half the length of each header brick is imposed upon the nextheader brick below.

VVith'the above and other objects in view, the invention consists in the construction, combination and arrangement of devices is hereinafter described and claimed.

The accompanying drawing is a perspective of a portion of a gas or coke oven wall constructed in accordance with this invention. Y

O In the figure of drawing, a designates the stretcher bricks and b designates the headers.

The stretchers a have recesses at the inner faces of the double wall, for interlocking with the transverse flue walls formed by the 5 headers b. These stretchers alternate with bricks 6, whose shape is roughly that of a hammer head, each brick I), having a projection 0, whereby'it is oined to one of the transverse bricks 6 The limbor projection 0 39 merges into the body of the brick Z) with a rounded oint on both sides, forming a thick, strong root, so that there is practically no risk of the limb breaking away from the body of the brick. y V V Those partsof the bricks b, which lie within the courses, constitute stretchers, not headers, and they may be of the same lengt-h as the stretchers a, in whi'ch'case the overlap throughout the wall amounts to half the ec length of the stretchers, thebest bond which can be obtained. 1 1 7 Each header brick is of less length than the space between. the outer surfaces of the courses and has a symmertical end arranged 45 between the opposing ends of two stretcher one .coursej andthe next such header brick bricks and extending to the outer surface 3 thereof and also has a symmetrical opposite end arranged in the recesses in the inner surface of two stretcher bricks of the opposite course and terminates short of the outer surface of the last named stretcher bricks, and the contiguous header bricks of eachcourse are reversely arranged, so that one such header brick extends to the outer surface of of the same course extends to the outer sur face of the opposite course.

Instead of using separatebricks b the limbs of the bricks b may be madeto extend right across the cavity, and thisjmay be ad vantageous where the thickness ofthe wall is not such that the limbs would require to be inconveniently long for that purpose; The symmetrical shape of the bricks or'blocks b is of advantage in that it reduces risk of deformation in the course of burning the bricks. i

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare that what I claim is 1. A gas or coke oven wall having fiues therein, said wall comprising courses of stretcher bricks certain of which haverecesses on their inner sides at their meeting ends, said courses being spaced apart and said wall also comprising header bricks connecting said spaced courses, each header brickbeing of less length than the space between theouter surfaces of the courses having a symmetrical end arranged between the opposing ends of two stretcher bricks and extending to the outer surface thereof and also having a symmetrical opposite end engaged in the said recesses in the inner surfaceof two" stretcher bricks of the opposite course and tends to the outer surface of one course and the next such header brick of the same course extends to the outer surface of the opposite course.

5 2. A wall as claimed in claim 1, wherein the limbs of the intermediate bricks merge into the bodies of said bricks with a rounded jpint on each side, whereby a strong root is formed.

in 3. A well as claimed in claim 1, wherein the intermediate bricks constitute stretchers of the same length as the plain stretchers.

In witness whereof I have signed this specification.
